You have scored a great internship with NASA, working on planning for an upcoming mission to Mars. The transfer orbit to Mars will last for several months and will require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen and 1.00 mol of methane as a byproduct. The methane is stored in a tank under pressure and is available to control the orientation of the spacecraft by controlled venting. A single astronaut exhales 1.09 kg of carbon dioxide each day. If the methane generated in the respiration recycling of three astronauts during one week of flight is stored in an originally empty 150-L tank at −45.0°C, what is the final pressure in the tank?

The result at a certain altitude is: R= 0.0915 kPa*km−1 Convert R to kJ*m−4 .arrow_forwardThe unit cell of platinum has a length of 392.0 pm along each side. Use this length (and the fact that Pt has a face-centered unit cell) to calculate the density of platinum metal in kg/m3 (Hint: you will need the atomic mass of platinum and Avogadro's number).arrow_forward
- Ceres is the largest asteriod in the Solar System.But with a mass of q.38 x 102º kg, a radius of 469.73 KM,and a maximum surface temperature of - 38.15°C it doesn't have enough gravity to keep an atmosphere.If the density of Ceres were to remain the same, what would its radius need to be (in kilometers) for itš escape velocity to the rms speed Of Hydrogen gas (H,) ot its maximum svrface temperature?arrow_forwardThe force P of magnitude 50 kN is acting at 215° from the x-axis.

Spectroscopic results indicate that the atmosphere, whose height is much smaller than the planet's radius, is largely helium, making the discovery truly controversial. Experts have deduced that helium is unlikely to be generated from the planet itself, therefore it is assumed that the helium in the atmosphere was created at the inception of the planet and is completely contained by its gravitational attraction. However, wide disagreement abounds about the composition of the planet. The surface of the planet is clearly composed of aluminum oxide, but some astronomers claim that this aluminum oxide is only a thin crust and that the planet is mostly iron. Given that the atmospheric temperature is 562 ∘C, calculate the minimum density ? of the planet so that its atmosphere could contain helium atoms. The molar mass of helium is 4.002 g/mol and the gravitational constant is…arrow_forward
- A tank containing water is pressurized with air to a pressure of 30 psig. With the pressure in the tank as the driving force, the tank is feeding water at a rate of 15 GPM to another tank at atmospheric pressure through a 1.5 inch line. What would the pressure in the tank need to be increased to in order to increase the flow to 30 GPM?arrow_forwardDetermine the dimensions in the vernier caliper illustrations in Figures C-66a and C-66b.

The z axis is directed upwards and the gravitational field is assumed to be uniform. 1) Using the fundamental principle of hydrostatic statistics, show that dp = -pgdz where p = p (z) is the gas pressure at height z. 2) If P_0 is the gas pressure at the foot of the pole, calculate the pressure p (z) at height z. 3) In the case of wind (M = 29 g / mol: R = 8.31J/ mol.k) at temperature T_0 = 300K, calculate the height of the poles necessary to observe the change in pressure (pressure at the threshold) at 5% .arrow_forward
- The most dangerous particles in polluted air are those with diameters less than 2.5 μm because they can penetrate deeply into the lungs. A 15-cm-tall closed container holds a sample of polluted air containing many spherical particles with a diameter of 2.5 μm and a mass of 2.6 x 10-14 kg. How long does it take for all of the particles to settle to the bottom of the container?arrow_forwardOn the surface of a hypothetical planet X, the atmospheric pressure is 4.25 x 106 Pa, and the temperature is 707 K. On the earth's surface the atmospheric pressure is 1.00 x 105 Pa, while the surface temperature can reach 320 K. These data imply that the planet X has a "thicker" atmosphere at its surface than does the earth, which means that the number of molecules per unit volume (N/V) is greater on the surface of planet X than on the earth. Find the ratio (N/V)X/(N/V)Earth.arrow_forwardLong-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1.21 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 155-L tank at −45.0°C, what is the final pressure in the tank?
